ESDA041-1JY, ESDA041-2W3Y Datasheet Automotive 4 V TVS for BMS in SOD323 and SOT323 Features AEC-Q101 qualified Low leakage current: 50 nA max. at 3.6 V Low clamping during hot plug surges Unidirectional devices Protection of 2 battery cells in 1 package ECOPACK2 compliant component ISO 10605 / IEC 61000-4-2: C = 150 pF, R = 330 , exceeds level 4 30 kV (air discharge) 30 kV (contact discharge) ISO 10605: C = 330 pF, R = 330 , exceeds level 4 30 kV (air discharge) 30 kV (contact discharge) IEC 61000-4-4 ISO 7637-3 Fast transient pulse a: Vs = -150 V Fast transient pulse b: Vs = +150 V Slow transient negative pulse: Vs = -85 V Slow transient positive pulse: Vs = +85 V Product status link Application ESDA041-1JY Protection of battery monitoring systems (BMS) in electrical vehicle and hybrid ESDA041-2W3Y electric vehicles such as e-bikes, cars and buses. The low clamping voltage during ESD and hot plug surges provides an efficient protection of the discrete and/or integrated MOS to ensure robustness and longevity of the battery management system. The low leakage current is compatible with a precise read-out of the state of charge of cells to maximize the global battery charge. Description These ESDA041 devices are unidirectional single and dual line TVS protection devices designed to protect battery monitoring system (BMS) and other circuits around batteries against ESD transients and hot plug-in overshoots. The dual TVS version in SOT323 provides space saving and cost effectiveness. These devices are packaged in SOD323 and in SOT323-3L.
